The Coffee Break App schedules your coffee breaks at the scientifically optimal moments — tracking your caffeine curve so every cup fuels you, and none of them steal your sleep.
What it does
A precision tool for coffee lovers who want to feel great all day — and actually sleep at night.
Watch your caffeine level tick down in real time. A dynamic graph shows exactly where you are on your metabolism curve — focus zone, plateau, and sleep-safe window.
Set your active days, preferred break times, and coffee habit. The app auto-schedules your next cup and sends a notification when it's the perfect time to brew.
When it's time, a focused break screen counts down your brew. Ambient sounds mark the start and end, keeping you present and refreshed before heading back.
Espresso, brewed, cold brew, or decaf — each type has a scientifically accurate caffeine profile. The app calculates your curve based on what you actually drink.
The app warns you when you're approaching jitter territory and shows your projected sleep clearance time — so you always know if that late afternoon cup is worth it.
Choose your active weekdays, coffees per day, break duration, and how far ahead you want your reminder. Your coffee habit, your rules.
The science
Using the standard pharmacokinetic model, the app simulates caffeine decay in your bloodstream — updated live, every second.
Simple by design
Set up once, run on autopilot. The app does the thinking so you can focus on your work.
Choose your active weekdays, how many coffees you drink per day, your preferred coffee type, and what time you usually start and end your day. Takes about 60 seconds.
The app calculates your optimal break windows based on real caffeine half-life science and fires a notification when it's time — not too early, not too late.
Open the app, tap Start Break, and a calming timer takes over. When it ends, a gentle bell sound signals you're ready to go — fuelled, focused, and on schedule.
